A theory is proposed to analyze the Raman band profiles of asymmetric top molecules in solution. Vibrational relaxation is assumed to arise from a pure dephasing process. Rotational relaxation is treated for the diffusional and free rotation limits and for the extended diffusion. The rotational diffusion results are obtained by applying the Van Kampen cumulant technique; corrections due to the fourthhyphen;order cumulant are given. Free rotation is studied by numerical methods. The extended diffusion is examined by applying the wellhyphen;knownJandMmodels to the asymmetric top problem. Representative band profiles are described according to the point group of the solute molecule.
